To all whom it may concern: I

Be it known that we, LEwIsS; VVHrrINe and WVILLIAM M. KoPrEs, citizens of the United States of America, residing at Mansfield, in the county of Richlandand State of Ohio, have invented certain new and useful Improvements in Auxiliary Cleaning Means for Bean and Pea Hullers, of which the following is a specification.

This invention relates to certain new and useful improvements in auxiliary cleaning means for bean and pea hullers, and the primary object of the invention is to pro.- vide improved means for separating the hulls from the grain; to provide means whereby the material is caused to positively move throughout the lengths of the screens so as to thoroughly effect separation, and means to receive the hulls and grain and direct their course of travel prior to depositing said halls and grain on the upper screen.

A further object of the invention is to provide means for alternately feeding the material to the ends of the upper screen at the time that each ofthe said ends is in raised position, and means for adjusting the mechanism for delivery on either side of the huller.

In the drawings: Figure 1 is a side eleva-,

tion of the invention, parts being broken away. Fig. is a top plan view, parts be ing brokenaway. V J Theflinvention'is shown'as used in connection with the side beams 1- of the frame of a bean and pea huller, from which beams depend U-shaped vertical supports 2, the free upper ends of which latter are pivotally connected at 3 to said beams 1.- The lower or horizontal portions oft-he supports 2 are movably connected to a. h-orizontalinain frame which latter consists of a centralbar 4 and end bars 5. An intermediate cross bar 6 is pivotally'secured to thecentral bar at of the horizontal frame by a pivotal bolt 7 and said bar 6 at one end is pivoted at 8 to a support 9. The opposite end of the bar 6 is pivoted at 10 to a pitmanll, the latter being connected to a crank arm 12 which is carried and operated by a vertical drive shaft 13. Underlying the horizontal frame and connected thereto is a bar 14 which has upwardly extending inclined arms 15 piv-otally connected to its ends, the upper ends of the arms 15 being connected to a cross rod 16 which extends through a board 17 The board 17 is secured on the under face of a delivery chute 18, and the latter is mounted in the box 19, the sides of the box 19 being provided with curved slots 20 in which the ends of cross rod 16 are received. A board 21 is secured to the under face of the chute 18 betweenthe ends of the latter and a rod 22 is secured at its ends to the sides of box 19 and passes loosely-through the board 21 so that the chute may have pivotal movement independent of the box 19.

The box 19 has a wire screen bottom 23 and a perforated metal screen 24 located above the screen 23. The rear end of the box is closed by means of a cap or hood 25 which extends over and closes the top side of the box at said rear end as shown in the drawings. A frame 26 supports the base or bottom of the box 19, and the frame 26 is supported by means of yokes or links 27 which are movably connected to the ends of the frame 26 and to the end bars 5 of the main frame. The front or discharge end of the box 19' has a pair of divergent spouts 28 and 29 attached thereto. A deflector wall 30 is arranged on andsecured to the upper screen 23 to deflect the hulls into the spout 29. A similar deflector wall 31 is arranged on the screen 24 and acts to deflect the pods into the spout 28, the walls being disposed so that they incline from the sides of the box toward apoint 32, which is common to the inner sides of each of the spouts 28 and 29.

The operation is as follows: The peas or beans are delivered onto the chute 18 and the latter causes same to be thrown to the rear end of the box 19 against the hood 25, by reason of its inclination toward the rear of the hood .25. Reciprocatory movement being imparted to the pitman 11 through the drive shaft'13 and its crank 12, effects oscillation of the cross bar 6 about its pivotal point 8 and such movement of the bar 6 is communicated to the main frame by reason of the pivotal connection 7. that said main frame has with the cross bar 6. The stated reciprocatory movement of the main frame, causes the box 19 to move from the full line position of Fig. l to the dotted line position shown in said figure, with the result that the peas or beans are effectively agitated and separated, the hulls being discharged through the spout 29, while the pods are discharged through the spout 28. WVhen the box 19 moves to the dotted line position in Fig. 1, in which its front end is raised, the delivery chute 18 is moved by the links 15 which are oscillated by the main frame to the dotted line position depicted in Fig. 1, which causes the front end of chute 18 to be lowered with the result that the peas are thrown against the raised front end of the screen 24. From the above it will be seen that the delivery chute 18 oscillates so that when. the front end of the screen 24: is raised, the front end of the chute is depressed, and when the rear end of the screen 24 is raised the rear end of the chute is depressed, with the result that the material is thrown to the extreme portion of the raised end of the screen, so that the material is thus assured of travel throughout the length of the screen so as to more effectively cause separation, and means are provided to deliver from either side of the huller.

What we claim is 1. In a device of the type set forth, a screen, means to oscillate the screen by alternately raising and lowering its ends, a de livery chute above the screen, and means to oscillate said chute so that when one end of the screen is raised the adjacent end of the chute is depressed.

2. In a device of the type set forth, a pivotally mounted screen, means to oscillate the screen by alternately raising and lowering its ends, and means to feed material alternately to the opposite ends and highest ends of the screen.

3. In a device of the type set forth, a pivotally mounted plane screen, means to feed material to the screen, and means to actuate the said elements, whereby when an end of the screen is raised, the material is fed to said end in a direction toward the highest point of said end. I

4. In combination with a box having a screen, means to alternately raise and lower the ends of the box, a centrally pivoted delivery chute, and means to alternately raise and lower the ends of the chute.

5. In combination with a box having a screen, means to reciprocate the box and to simultaneously raise and lower its ends, a delivery chute pivoted to the box between the chute ends and between the ends of the Copies of this patent may be obtained for box, and means operated by said box actuating means for alternately raising and lowering the chute ends.

6. In combination with a horizontal main frame, and means to reciprocate said frame, a box having a screen, links pivoted to the ends of the box and to the main frame to permit the box ends to be alternately raised and lowered when the frame is reciprocated, a chute pivoted between its ends to the box between the ends of the latter, links connected to the frame and to the chute for raising and lowering the ends of the chute,

frame is reciprocated, means to support the frame to permit reciprocation thereof, a delivery chute pivoted between its ends to the box at points between the box ends, links connected to the frame, the box sides having curved slots, and means carried by the links and extending through said slots to eifect raising and lowering of the chute.

during movement of the box and frame.

8. In comblnation with a screen pivotally mounted for reciprocation and a frame,

7 means to reciprocate the screen and to, simultaneously and alternately raise and lower the ends thereof to receive the grain or the like at its highest end, and a deliverychute mounted on the frame and adapted to be raised and lowered.

9. In combination with ascreen, means to reciprocate the screen and to alternately raise and lower the opposite ends thereof, and means to alternately feed the material to each end of the screen when said end is in raised position.

In testimony whereof we aflix our signatures in presence of-two witnesses.
